Answer:

95>=X <=100. More or equal to 95 or equal or less than 100.

Step-by-step explanation:

The Total of the first score is needed first

81+87+ 94+93=355

The total of this score

Let X be the 5TH score we are looking for

(355+ X)/5= 90

355+X= 450

X= 450-355

X= 95 the person needs to sore between 95 and 100 ( which is the highest possible score).

What is the math problem answer?
azamat

To find the mid point add both X coordinates together and divide by 2 and then do the same with the y coordinates.

X coordinate: 4 + -6 = 4-6 = -2 / 2 = -1

Y coordinate: -2 + 3 = 1 / 2 = 1/2


Midpoint: ( -1, 1/2)

Solve :<br><br> 5x - 7y = 12<br><br> 5y - 2x = - 7
Afina-wow [57]
There is one solution:

use elimination method

5x - 7y = 12
5y - 2x = -7    ---> change equation around

 5x - 7y = 12
-2x + 5y = -7

2 x ( 5x - 7y) = 2 x (12)    multiply both sides by 2
5 x (-2x +5y) = 5 x (-7)

this give you
 10x - 14y =24 
-10x+25y = -35                    add down
-----------------------------
        11y = - 11                    x is eliminated to find y value
           
            y = -1                         input to one of the original equations

5(-1)  - 2x = -7

-5  - 2x = -7
+5           +5                       add 5 to both sides
----------------------------
-2x = -2
    x = 1

your coordinates for when they intersect is at (1, -1)
one solution
